The jQuery DD_belatedPNG plugin is a direct port of DD_belatedPNG, which allows you to use 24-bit alpha-translucent PNG images in image tags as well as for the background-image CSS property in Internet Explorer 6, supporting background positioning and background repeating. There is no usage of AlphaImageLoader, so this doesn't have the buggy z-indexing associated with that filter, and it responds to Javascript element.style assignments and the :hover pseudo-class.
